Simple sequence repeats (SSRs) or microsatellites constitute a countable portion of genomes. However, the significance of SSRs in organelle genomes has not been completely understood. The availability of organelle genome sequences allows us to understand the organization of SSRs in their genic and intergenic regions. In the current study, the mitochondrial and chloroplast genomes of different taxa of plants were... Read more.

It is very important to improve the design of the real-time operating system (RTOS) especially if we want to use it in some special devices. Numerous researches have accepted conventional RTOS as being the customary approach for designing devices used by children. This is because these are able to facilitate the implementation different criteria such as clustering, stability and alternate programs. In this paper,... Read more.

In this work a comprehensive solution for the Gatanga Water Trust (GWT) has been developed to assist it in managing its water supply and distribution. The solution comprises two subcomponents: a mapping component and a billing component which are tightly coupled together. The proposed system uses stable open source products for the mapping component and the database. At present the GWT uses outdated maps and... Read more.

Mobile ad hoc networks (MANETs) consist of a collection of wireless mobile nodes which dynamically exchange data among themselves without the reliance on a fixed base station or a wired backbone network. All nodes are mobile and can be connected dynamically in an arbitrary manner. There is no static infrastructure such as base station. All nodes of these networks behave as routers and take part in discovery... Read more.

Recently, authors established a number of inequalities involving Khatri-Rao product of two positive matrices. Here, in this paper, the results are established in three ways. First, we find new Holder-type inequalities for Tracy-Singh and Khatri-Rao products of positive semi-definite matrices. Secondly, the results are extended to provide estimates of sums of the Khatri-Rao and Tracy-Singh products of any... Read more.

Technology has moved from a level at which a user is always present in a place before he/she can control or do anything at the place. Imagine what television used to be before the inception of remote control. With the inception of remote control, the television can be controlled while lying on the bed or sitting down on the chair. You do not have to move towards it and press the button on it before you can... Read more.

Artificial neural networks (ANN) have been developed as generalizations of mathematical models of biological nervous systems. Generalized regression (GR) and multiple linear regression (MLR) models for shelf life prediction of dairy product were developed. Results of both the models were evaluated with three types of prediction performance measures viz., mean square error, root mean square error and... Read more.

Fiber Raman amplifiers (FRAs) are attractive for ultra wide dense wavelength division multiplexing (UW-DWDM) transmission systems due to their advantages of broad amplification bandwidth and flexible central wavelength. With recent developments of optical pump sources with high power near 1.4 μm wavelength and highly nonlinear fiber having a peak effective Raman gain coefficient, more than ten times that...

Iris recognition is one of the most accurate identity verification systems. Since its initial introduction by J. Daughman, many methods have been proposed to enhance the performance. We present an overview of the latest research on iris recognition by categorizing the research in four groups outlined as localization, segmentation, coding and recognition. We present the latest developments explaining advances to solve... Read more.

On distributed memory electronic computers, the implementation and association of fast parallel matrix multiplication algorithms has yielded astounding results and insights. In this discourse, we use the tools of molecular biology to demonstrate the theoretical encoding of Strassen’s fast matrix multiplication algorithm with DNA based on an n-moduli set in the residue number system, thereby...

The emphasis for the use of wireless LAN in industry is on robustness, reliability and security. Almost any given single secruity mechanism (such as MAC filtering) alone may be easily overcome by attackers. However, proper configuration and implemetation of the maximum possible security mechanism must be used to form a multiple security layers, to provide the best possible wireless protection. The present paper... Read more.

An indoor positioning system was developed to provide a fast and easy determination of unknown position coordinates. Wireless sensor nodes (WSN) are employed in a test area. Trigonometry techniques were employed to determine the position of the unknown objects by employing numerical analysis techniques on received signal link quality indicator (LQI) values. The distances between the unknown object position and the WSNs... Read more.
